Soil Sampling Data for the Exide Preliminary Investigation Area

The Department of Toxic Substances Control (DTSC) is committed to cleaning up lead-contaminated soil at residential properties, schools, parks, day care centers, and child care facilities with the highest levels of lead in soil and the greatest risk of exposure within the Preliminary Investigation Area (PIA). The PIA is defined as an area encompassing an approximately 1.7-mile radius surrounding the former Exide Technologies, Inc., (Exide) battery recycling facility in Vernon, California. DTSC’s top priority is protecting the health and safety of people in the community, especially the youngest and most vulnerable. DTSC plans to clean up approximately 2,500 parcels within two years of the start of cleanup activities.

Soil Sampling Data Map

DTSC is prioritizing the cleanup of properties with the highest levels of lead in soil that also pose the greatest risk of exposure. Criteria for the cleanup prioritization for the next phase of the cleanup can be found in the Final Removal Action Plan (Cleanup Plan), see Page 3-2. Residents and owners can enter their address into the map tool (below) to view their sampling results and see if their property meets the criteria for prioritization during the next phase of the cleanup.

Soil Sampling Data Tables

DTSC has sampled approximately 8,500 parcels within the PIA as of August 30, 2019. DTSC is sharing data tables that have location-specific sampling information for these parcels. These tables provide the representative soil lead level for each parcel as well as readings taken at various locations and various depths. For each parcel sampled, DTSC has already provided the owners and residents their sampling results.

For details regarding how to use the data tables, view or download the “How to Use the Data Tables” instructional document. Note: the file size for the data tables is large (48 MB).
